拓宽利用的空间
许多向我们提出的设计房屋的要求都伴随着一个前提条件，即确保在一个极其细分的地段为一个核心家庭设计房屋，对此我们不能轻易应用在日本积累了很长时间的建筑方式。我们在设计时反复试验，因为我们认为我们正处于一种新方式的形成期。

Widening interspace to utilize
Many of the requests to us for designing a house are accompanied with a prerequisite of ensuring a house for a nuclear family at an extremely subdivided lot, to which we cannot easily apply the manners of architecture having been accumulated for long time in Japan. We repeated trials and errors while designing as we think we are in the formative period for a new manner.

这一次也不例外。对于这种密度的城市房屋，相邻房屋的外墙互不接触，民法要求外墙后退500毫米，在这些墙之间形成1000毫米宽的空间。

This time was not the exception as well. For this level of density of urban houses, where outer walls of the adjoining houses do not touch each other, the civil law demands 500 mm setbacks of outer walls to form interspace of 1,000 mm in width in-between those.

我们一直在思考是否可以更有效地利用它。在这个项目中，我们从东北部相邻土地的边界线上增加了400毫米的后退。因此，有1400毫米宽的空间作为通道，从相邻地块的边界算起有900毫米的宽度，通过在面向空间的侧墙中间放置一个入口来加以利用，这实现了房屋内的路线空间最小化。

We have kept thinking if it is used more effectively. In this project, we gave 400mm more setbacks from the boundary line of the north eastern adjacent land. As a result, there was 1,400mm wide interspace as a passage, which was 900mm in width from the border of the adjacent plot, utilized by placed an entrance in the middle of the side wall faced to the interspace, which realized to minimize space for routing in the house.

后退确保了屋檐高达约9米，避免了北侧的斜线。非结构墙被向外推开，为壁橱等提供了空间。因此，它提供了更大的空间，包含厕所等设施，而不是从室内空间如家具看起来的那样，这带来了空间感知的模糊性。

The setback ensured the eave as high as about 9 m avoiding the north side slant line. Non-structural walls were pushed out outward providing space for closets,etc. Accordingly, it provided bigger space containing facilities such as a toilet than as it looked from interior space like furniture, which brought ambiguity in perception of space.

建筑和家具
当我有幸看到建筑师设计的房子时，我有时会觉得设计的家具似乎在传递信息。我不知道用 “尊重原来的空间，不要带任何不必要的东西 “来概括是否正确，但它似乎几乎是一个强烈的愿望，就像说不要用任何不值得的东西填充空间一样。虽然我不能说我完全没有这样的愿望，但我的目标仍然是创造一个空间，让各种东西可以被带进来，并在日常生活中更自由地使用。

Architecture and furniture
When I have the honor of seeing an architect-designed house, I sometimes feel as if design furniture is telling messages. I wonder if it is right to summarize by saying “respect the original space and don’t bring any unnecessary things”, but it seems almost like a strong desire as much as to say not to fill the space with anything does not deserve it. Although I cannot say I don’t have such desire at all, I still aim to create space where a variety of things can be brought in and used in everyday life much more freely.

在这所房子里，建筑元素，如楼梯、洗衣空间、壁橱、扶手和马桶都被做成了家具的样子。除了这些，只有地板。因此，建筑和家具是混合在一起的，这些意义是相对的，在这种情况下，我一直试图在房间里创造自由，好像所有这些只是随机放置和使用的机会。

In this house, architectural elements such as stairs, a laundry space, closets, hand rails and toilets are made as if those are furniture. Except for those, there are only floors. As such, architecture and furniture are mingled and those meanings become relative each other, in which way I keep trying to create freedom in rooms as if all of those are just randomly placed and used by chance.

就像编排笔记一样
我一直认为处理楼梯的方式在房子里很重要，特别是在小房子里。一般的方法之一是在一个房间的中间放置一个楼梯，在两边分配功能。虽然它最大限度地提高了使用面积，但它留下了一个问题，即是否能带来丰富的空间体验，让人们在生活中一直看到房子的每一寸空间和楼梯。

Like choreography notes
I always think the way of dealing with stairs is important in houses, especially in small ones. One of the general methods is to place a stair at the middle of one room allocating functions on both sides. Although it maximizes usable area, it leaves the question if it brings rich spatial experience to live seeing every inch of the house and a stair all the time.

这个房子里的餐厅的天花板高度是3776毫米，这是为了使楼梯平台下的空间可以作为路由使用。通过使其极薄，其余的高度被分为向下1880毫米和向上1850毫米。虽然这些尺寸很紧，但你可以在两层之间穿行，注意你的头。

The ceiling of the dining room in this house is 3,776 mm in height, which is determined to make the space under the staircase landing usable as routing. By making it extremely thin, the rest of the height was divided into 1880mm downward and 1850mm upward. Although those are tight dimensions, you can go through between two layers minding your head.

我认为对于一个房子来说，有这样的物理体规模是有利的。因此，餐桌被放置在一楼和二楼之间的楼梯上，为居民留下空间从下面通过。当居民上下楼时，身体在桌子下出现和消失。

I think it is favorable for a house to have such a scale of physical bodies. Therefore, the dining table was placed over the stair between the ground floor and the first floor leaving space for residents to pass under it. Bodies appear and disappear under the table as residents go up and down the stair.

一旦你推开入口的门，溜进家具里面，你就会到达餐桌下面，那里面对着一堵大墙，接受从南面窗户射来的阳光。当你踩在小凳子上时，你看到白色的墙从北面柔和地照过来。到了二楼，你踩着沙发、像抽屉一样的家具，还有细细的楼梯。在向楼上走的每一步，光线条件随着方向和空间大小的变化而变化。楼梯是对这个小而薄的空间的空间体验的编排。

Once you slide the entrance door and slip into inside of furniture, you reach under the dining table, where faced to a big wall receiving sun light coming through the south window. You see the white wall softly lit from the north as you step on the small stool. To the second floor, you step on the sofa, furniture like a drawer, and the thin stair. At every steps toward upstairs, light conditions change as the direction and the size of space change. Stairs as choreography for spatial experience of this small, thin space.

结构
由于场地位于狭窄的死胡同后面，车辆的运入受到限制，因此采用了轻型材料的结构，如100mm×100m的H型钢做柱子和横梁，圆钢做支撑，75mm的甲板板做地板结构。这使得钢材料的数量减少，总的建筑成本与木结构房屋的成本差不多。

Structure
As the site is located in the back of a narrow cul-de-sac and carrying-in by vehicle was limited, the structure with light materials such as 100mm×100m H steel sections for columns and beams, braces with round bars,75mm deck plates for the floor construction was applied. Those resulted in reducing the amount of steel materials, and the total construction cost to about as same as that of a wooden house.

楼板的水平刚度是由6毫米的扁钢和甲板板凹陷部分下面的50毫米的方形拉杆梁组成的水平支撑获得的。不同楼层的地板在两端被固定在柱子上，这样就可以保持它们之间刚度的连续性。

The horizontal stiffness of floors was acquired with horizontal bracings of 6mm flat bars and 50mm squared tie beams beneath concave parts of the deck plates. Floors on different levels were fixed to the columns at both ends so that the continuity of stiffness between those was still kept.
